Macy’s(M) said it expects to layoff about 3,900 workers as a result of the upcoming store closures, and another 6,200 jobs will be cut as the company works to streamline its management team, according to a press release.

A few stores have already been shuttered, but 63 will close down between now and mid-2017, leaving about 660 U.S. stores left open. The closings are among the 100 stores Macy’s said last August that it intends to shutter.
